CERN Open Data Datasets Browser

Browse and filter CERN Open Data collision and simulated datasets by experiment, publication year, collision energy, and keyword. Returns only records of type Dataset (66,000+ datasets). Useful for finding specific NanoAOD or MiniAOD simulation samples, real collision data, or derived datasets for a given LHC run period. LHC Run 1 data: 2010–2012 at 7–8 TeV; Run 2 data: 2015–2016 at 13 TeV. Experiments: CMS (57K+), ALICE (171), ATLAS (184), LHCb (7K+), DELPHI (12K+). Supports pagination for large result sets.
